Fig. 7 a broken elevational ing jaw 8 which is connected with the main view of'the seal or stopper-chute and a-ssojaw by a pivot 9'. The main jaws 8 as also ciated escapement device. Fig. 8, a sectional the member 6 are recessed to accommodate View taken as indicated at line 80f Fig. 7 the'bottle-neck. Each auxiliary jaw 8 com- 55' Fig. 9, an enlarged "broken sectional view prises a neck-engaging segment- 10 and a shank 10, 'the"s hank being housed in a slot 1n the mam jaw. Each segment 10 carries a; stud 11 to which is attached one end of a .coil spring llfiwhose opposite end is attached to a stud 11 carried by the main jaw 8. The auxiliary jaws may be opened (see Flg. 5 to admit a bottle-neck 12, and

' will be hel open by the springs 11 which as y at this time willbe outof line with the pivots 9. When the bottle-neck-is insert-- ed, the auxiliary jaws are thereby swung to the closed position (Fig. 4) andthe spr ngs- The opening- 11 tend to hold them thus. movement. of the auxiliary jaws is limited b the shoulders 10- which engage the rear walls of the slots. The concave portionsof the segments 10 are provided with brassm- I serts 10,; which are. suitably recessed or countersunk,;to engage and hold the external flange of the' bottle-neck. The main jaws 8 are normally held in the open position by a s ring 13 which connects their shanks, as shown in Fi .4. The shanks of the jaws 8 are rovi ed with beveled surfaces 14 --adapte to be'engaged by the tapered lower 7 end 15 of a jaw-locking plunger 16 mo-unt- 3 ed in a tubular plunger 17 whose upper or rear end is equipped with a roller 18 which engages the elbow portion of the lever E. The plun er 16 is held yieldably projected .with relation to the member 17 bya spring 19. It will be noted that when the rod D is' drawn downwardly to cause the tool B to rform the stoppering operation, the plunger 16 will be forced between the shank portions of the 'm'ain'jaws 8, vthereby cau'sigig a slight movement ofsaid jaws which is sufliclent to cause the auxiliary jaws 8 to securely clamp the :neck of the bottle. Thus, while the auxiliary-jaws will open wide to admit the bottle-neck by a lateral movement and'will swing to a closed position during the insertion of the bottle the final clamping action is secured by 'the slight automatic closing action of the main jaws which is effected by the plunger 16.

.' plunger 24 which The rear end of thelever E is mounted on .a pivot 20 with which the frame member A is equipped in therear of the upper end of the rod D This is shown in detail in Fig. 10',W11,.ere the, pivot 20 is shown secured to the'frame member by a set-screw 21. One end of the pivot 20 is equipped with ahead 22 providedwith a vertical perforation 23 which affords a guide. for the lower end of a forms a part of the device the stopperselecting d F for rotating vice F.

The stopper-selecting device F need not be described in detail 1n the presentapplication. It will suffice to explaln that it comprises ,a frusto-conical" rotary hopper 26 which is secured to rotate with a shaft 27 ated y a pawl-29 carried by n collar 30 ed with a" ratchet wheel 28 and actuwhich is oscillated by the plunger 24. When the plunger 24 is depressed, the pawl 29 serves to actuate the shaft 27 through the medium of the ratchet wheel 28; and when the plunger 24 rises, the pawl 29 rides idly over the ratchet teeth to gain a fresh hold on the ratchet-teeth. The hollow member 26 isfixed to and rotates with the shaft '2? and with the shaft also rotates a disk 31 which virtually closes the enlarged end of the rotary hopper '26 and is equipped at its innervertical face with a series'of permadeliver those seals which are properly presented to the upper end 32 of the seal-chute F. No claim is made in the present .application to the details of construction of the stopper-selecting device F. It may be ;in mass to the rotary hopper 26 through a charging chute 33. The operation of the device is to take the stoppers or seals from the interior of;the rotary member 26 and deliver them, properly arranged, to the chute F, which is thus kept filled with seals.

capement device G, which will be understood by reference to Figs. 3, 7 and 8. The ;escapement device G comprises a pair of esicapement members or pawls 34 located in :recesses vwalls of the chute F is provided, the mem- {bers 34 beingsupported on pivots 36. -Each -nent magnets (not shown), which serve to added, however, that stoppers are delivered.

The seals descend by gravity to the es.

35 with which the lateral or edge a member 34 has a vlower stopper-engaging ftooth 37 and an upper stopper-engagmg *tooth 38. The members 34 are also proivided with actuating arms 39' adapted to be elevated by fingers 40 carried by a rock- Zshaft 41 which is equipped with an actuating arm 42. The actuating arm 42 is joined by which is adapted to be moved downwardly by a yielding finger or spring 45 which is actuated by thespring'46j and in this action the arms 39 of the members 34 are lifted, thus permittin the stopper which is held between the mem ers 34 to drop.

I The lower terminus of the chute F comprises a curved chute section 48 carried by fa bridge-piece 49 mounted on the member ,6 of. the bottle-supporting device. The channel 50 of the chute section 48'is interfascends, the slide 44,moves upwardly, being .10. a link 43 to the Lower end of a slide 44 4 which is joined 'draws the sleeve 52 'cepted by an inclined perforation 51 throu h which the stoppering tool works. It will e understood from Fig. 3 that when-astopper descends to the lower portion of the channel 50, it will bevmaintained in position to be inserted in the bottle-mouth by the stoppering tool.

The pawlactuating plunger 24, as has been indicated, works on the down stroke to rotate the hopper 26 and the magnet-carrying disk 31. To accomplish this purpose in the best manner, the plunger 24 is equipped with a sleeve 52 which carries a pivot 53 to lower-end is connected, by a pivot 55 (see Fig. 3). to the upper end of tool plun er B. One lateral wall of the guide E is provided with a slot 56 which permits movement of the wrist-pin or stud 55. Above the sleeve 52 a collar 57 is secured on the rod 24; and below the sleeve 52 a end of said springresting upon a collar 59 which is secured to the rod 24. When the plunger B descends, the connecting rod 54 v of the spring 58; and the spring 58 acting.

86 with a composite tool 60 which is adapted to insertartificial stoppers or seals 61.

stopper of this which on the rod 24 serves I the purpose 7 of applying to actuate the shaft 27 with less suddenness of motion than would occur were the spring 58 omitted. I the foot-treadle to an intermediate portion The improved machine may beadapted to or insertin seals or stoppers of any desired form. nythe illustration given, the operative end of the stopper-applying plunger B is equipped A form comprises acap disk carries a sealing disk and is surmounted b a locking ring or retainer ring which is a apted to engage an internal locking shoulder in a bottle-mouth. It is unnecessary to describe the stopper-inserting tool in detail. I

From the description given it w ll be understood that when an, operator inserts a bottle in the neck-clamping jaws 8 and depresses the foot treadle 3, the lever- E will wardly, thereby causing be swung downwardly about the pivot 20, thereby forcing the locking plunger. 16' to close the jaws 8'. Inthe same movement, the inclined plunger. B will be forced down the tool to effect the insertion of the stopper which rests at the lower end ofthe channel 50 of the stop-- per'chute. When the plunger B descends,

'- the finger 45 carried by the upper end thereof-forces the slide 44 downwardly, thereby causing the fingers 40 to swing downwardly,

so that the escapement members 34-will turn on their pivots to withdraw the upperteeth 38 and admit a fresh stopper between the pawls. 'When theplunger B ascends, the escapement members 34 will be permitted to turnto the position shown in Fig. 5, thereby a connecting rod 54, whose the stoppering down against the force cable in said guide,

frotary member, mg to impart motion to said rotary member permitting the fresh stopper to drop to the lower end of the channel 50, where it rests in position to be forced into a bottle-mouth at the next operation.

In the operation of the improved machine, the spring 1 serves only to elevate the connecting rod D and the stoppering plunger B, so that the spring may be a. comparatively light one, thus rendering the work of depressing the foot-treadle lighter than it would he were aheavier {spring to' be em-' ployed. This follows from the fact that it devolves upon the stopper-applying plunger -B merely to actuate the operating devices F throughan idle movement to engage the pawl'29 with' a fresh tooth of the ratchet wheel 28.

The foregoing, detailed description has been given for clearness of understanding only, and no undue limitatlon should be 'understood therefrom.
